CHARLES LEISOHER, OF EASl PIERRE, SOUTH DAKOTA.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 488,078, dated December13, 1892.

Application filed August 2 1892.

To all whom it may concern:

Be it known that 1, CHARLES LEISCHER, a citizen of the United States,residing at East Pierre, in the county of Hughes and State of SouthDakota, have invented certain new and useful Improvements inCar-Couplers; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to car-couplings and its object is to make thesame auto maticthat is-to say, to produce the coupling by the simpleintroduction of the link, extending out from one of the draw-heads onone car into the other car when the cars are pushed together. It has forits object, moreover, to so construct the parts that the rain and waterwill be shed off from the interior of the drawheads, and thus protectthe interior mechanism of the coupler against corrosion and otherinjurious actions.

For this purpose my invention consists in the features and combinationof parts hereinafter set forth and covered in the claims.

In the drawings accompanying this specification, Figure 1 represents avertical longitudinal central section of a coupler embodying myinvention. Fig. 2 represents a perspective view of one of the draw-bars;and Fig. 3 a transverse vertical section on line 3 3, Fig. 1.

By referring to the drawings it Will be noted that the draw-bars A A,which are of any ordinary or suitable construction and which may beattached to the cars in the usual way, are provided with the usualdraw-heads having abell-shaped mouth A, and are, moreover, formed withthe vertical transverse slotsa a in the top and bottom of the draw-bars,respectively. Each draw-bar is provided at its top with a yoke B,pivoted at its rear at b, and having a rearward extension 12', wherebyits yoke is adapted to swing upwardly in a vertical plane, the upwardmotion being limited by the rear extension I). A coupling-pin O ispivoted to and depends from the front end Serial No. 441,990. (Nomodel.)

of each yoke B at its under side and is provided with a lug 0, extendingforwardly and limiting the motion of the pin in a forward direction bybearing against the'under side of yoke B. This coupling-pin (J in thenormal position of the parts extends downwardly through both slots atand a, as shown at the left side of Fig. 1, and thus serves to lock thecoupling-link D in position. The upper surface of each draw-bar isprovided with two retaining-ribs 01. 0. with which two correspondinglongitudinal grooves b b on the under side of the yoke B are adapted toengage, as best shown in Fig. 3, and thereby prevent anylateral play ofthe yoke, whereby damage to the mechanism may result.

The yoke B extends entirelyover the upper side of the forward part ofthe draw-bar A, and is preferably beveled off at the sides and front, asshown at b so as to shed the water and prevent its access to theinterior of the draw-bar and consequent damage to the operating parts.

A chain E may be attached to the upper faces of the yokes to raise thesame for uncoupling, and these chains may be carried to any convenientpart of the car where it can be handled by the brakeman conveniently andwithout danger or risk to himself.

The operation of this coupler is apparent from the foregoing. When a caris pushed toward another, the link D from one drawhead enters the mouthof the other drawheadand pushes the coupling-pin 0 rearwardly until itpasses the same, when the said coupling-pin will drop back into thevertical position and lock the link, thusefiecting the coupling. When itis desired to uncouple the car, the yoke Bis simply raised by the chainE, or otherwise, thus permitting the link D to be withdrawn.

What I claim, and desire to secure by Letters Patent, is

1. In a car-coupler, the combination of a draw-head having longitudinalslots in top and bottom with a yoke pivoted to the top of. the draw-headand a coupling-pin depending from the under side thereof and providedwith an upper forward lug, as 0, adapted to draw-head, and acoupling-pin depending bear against the under side of the yoke to fromthe yoke, substantially as set'forth. IO limit its motion, substantiallyas set forth. In testimony whereof I aflix mysignature in 2.
